Towards Sustainable Buildings: Novel Strategies for the Design of Vibration Resistant Cross-Laminated Timber Floors

Conventional building materials (concrete and steel) produce approximately 9% of annual global carbon emission. Carbon emission in civil engineering can be drastically reduced by using wood. Recent technological advances and new construction techniques have led to the development of new natural composite material called cross-laminated timber (CLT), a compelling alternative to the concrete and steel, providing a low carbon footprint and comfortable living conditions.

As a lightweight material, CLT is particularly prone to human-induced vibrations, causing vibration serviceability issues such as annoyance to human occupants and dysfunction of vibration sensitive equipment. To become competitive with concrete and steel in spanning large open space areas in buildings, long-span CLT floors are needed. By using the conventional CLT floor solutions, long-spans are relatively hard to achieve due to the limitations of timber mechanical properties. Therefore, novel strengthening techniques of CLT are required.

Substrate4CLT aims to deliver sustainable and cost-effective solution for vibration resistant CLT floors primarily designed for large open-floor areas in commercial buildings. This will be achieved by:

  • proposing novel strengthening methods of CLT floors;
  • providing scientifically supported information on their dynamic performance through numerical and experimental simulations by using a unique walking and jumping force models;
  • developing vibration-based methods and tools for their implementation in the design and construction.
